Hair pulling device

A hair pulling device, comprising a machine body which is provided with a hair clamping support and a driving device, wherein a fixation shaft which is fixed and non-rotary as well as a plurality of positioning frames which are driven by the driving device to rotate around the fixation shaft are disposed on the hair clamping support;

• a plurality of groups of hair clamping assembly units which are rotated with the positioning frames are disposed, along an axial direction of the fixation shaft, on the positioning frames;
• the hair clamping assembly units are pincer-shaped;
• the fixation shaft is fixedly sleeved by a positioning shaft;
• a column of first guide raised rail sections extending radially are axially distributed on an upper part of the positioning shaft;
• the first guide raised rail sections are in corresponding fit with lower parts of the hair clamping assembly units;
• the hair clamping assembly units are rotated with the positioning frames;
• and through extrusion driving of the first guide raised rail sections on the positioning shaft towards the positions under the hair clamping assembly units, closing and clamping actions of clamping mouths on upper parts of the hair clamping assembly units are realized;
• and
• wherein a column of second guide raised rail sections extending radially are distributed axially on a lower part of the positioning shaft;
• the first guide raised rail sections and the second guide raised rail sections are arranged in a staggered manner on an axial position;
• the second guide raised rail sections are in corresponding fit between the two adjacent hair clamping assembly units;
• the second guide raised rail sections on the positioning shaft are extruded between the two hair clamping assembly units, so that opening actions of the clamping mouths on the upper parts of the hair clamping assembly units are realized;
• first guide parts which guide each hair clamping assembly unit to be gradually opened and closed and are conical are disposed on both ends of each first guide raised rail section;
• and second guide parts which guide each hair clamping assembly unit to be gradually opened and closed and are conical are disposed on both ends of each second guide raised rail section.
